The new chemical oscillator has been recently constructed with the help of DNA components. Following specific instructions, DNA molecules could offer larger précised molecular control for synthetic chemical systems, which is the discovery of creating molecular machines with complex and new behaviors.


A chemical oscillator and chemical amplifiers have been created by a team of researchers with a systematic process having potential of embedding sophisticated circuit computation in to the molecular systems dedicated for major applications in sectors such as health care, nanotechnology and advanced materials. The research has been published in the Science journal issue of December 15.

David Soloveichik, a leading researcher of the studies and his associated team at The Cockrell School of Engineering at The University of Texas, Austin disclosed theory about programming the synthetic oscillators as well as other systems, building DNA molecules that obey particular instructions.

An Assistant Professor, David Soloveichik from the Cockrell School’s Department of Electrical and Computer Engineering with a graduate student, Niranjan Srinivas from The California Institute of Technology and co-authors of the study have successfully designed the first chemical oscillator of its type which uses DNA components, with no enzymes, proteins or other cellular components demonstrate that just DNA is capable for complex behavior.

Soloveichik said in a statement that, “DNA can be used in a much more active manner. We can actually make it dance — with a rhythm, if you will. This suggests that nucleic acids (DNA and RNA) might be doing more than we thought, which can even inform our understanding of the origin of life, since it is commonly thought that early life was based entirely on RNA.”
